TAR & CHIP GUIDELINES__________________________________________________________




The great news about your tar and chip surface is that is virtually maintenance free! But no roadway surface is truly maintenance-free. In order to help maintain the life of your tar and chip surface we are providing some information and recommendations for its care. As always, if you have any questions, please do not hesitate to contact us! You can view these guidelines anytime on our website.

Tar and Chip needs a little time to bond. You will be able to drive on your surface immediately but please stay cautious for the first few weeks and drive slower than usual. Driving over the surface area helps the chips and tar bond. The more layers of tar and chip, the more permanent your surface will be. Since it will take months for the tar and chip to fully bond it is important to avoid the following:

  • Do not sit in one spot and turn the power steering on any vehicle, riding mower or all terrain vehicle. If you do, you may cause power steering marks and ruts in tar and chip that will not go away and will leave holes in your new driveway.
  • Parking motorcycles and bicycles on the driveway where a kickstand can penetrate the surface.
  • Parking a trailer or RV on the surface without putting a piece of plywood beneath each wheel and hitch to evenly distribute the weight.
  • Do not drive off the edges of your driveway with any car, riding mower or all terrain vehicle. These edges need time to set up.
  • Spinning donuts with a vehicle, mower or all terrain vehicle. This will cause ruts in your surface.
  • The sides of your driveway should be backfilled with topsoil; grass should be seeded up flush with your driveway. If this is not done in a timely manner, the edges that are exposed may start to crack.
  • There will be “loose stones” on top of your driveway for a few months. After a minimum of 3-6 months (it may take up to 1 year; depending on how much traffic is traveled on the driveway) most stones will have “settled” into the tar. You may sweep these loose stones off or you may contact our office and we can provide stone sweeping services.
  • When mowing the lawn, avoid spraying the grass clippings toward the tar and chip surface area.
  • On very hot days you may notice the tar heating up again. This is normal. It is rare, but can happen. Just use extra caution on these days when walking or riding on the surface.

Weeds: On the first couple layers of tar and chip you may still get weeds growing through the driveway. This is normal! You will need to use weed killer on these spots or pick them out. The more shaded your driveway, the more likely this may happen. The more layers of tar and chip you have on your driveway, the less chance of this happening.

Snow Removal: If you use a plow truck or snow blower you will want to be careful not to dig up the stones or the driveway. We recommend NOT plowing the first snow so this can be compacted and used as a “protector”. Keep the plow 1 inch above the surface. Remaining snow will melt and drain through the surface.
